Computational Tools for Re-Entry Aerothermodynamics: Part II. Surface Ablation

Abstract

An extension of the recently developed numerical model for surface ab lation is reported here. In order to capture the chemical processes happening insid e the char and the pyrolyzing zone, equilibrium chemistry and finite-rate chemi stry modules have been incorporated into the numerical model. The developed numerical model is then validated using standard benchmark test cases available from the lit erature. A detailed discussion about the results is given, followed by a brief note on th e ongoing future work.
